Answer 1

Answer:

Short term: The fish (that sharks feed on) increase, the aquatic plants decrease

Long term: The fish (that sharks feed on) decrease, the aquatic plants increase

Explanation:

Short term: The fish increase because the sharks that used to feed on them decrease hence they get eaten less. The increased fish eat a lot of plants hence aquatic plants decrease.

Long term: The increased fish will then compete for the few aquatic plants present. Only the stronger fish survive hence most fish starve and die. Less fish means that the aquatic plants are being eaten less thus the aquatic plants increase.
